<p>A wrapper for parsers that provides the operations that must be supported by all parsers (e.g. <code class="computeroutput">operator&gt;&gt;()</code>). <code class="computeroutput">GlobalState</code> is an optional state object that can be accessed within semantic actions via a call to <code class="computeroutput"><a class="link" href="namespaceboost_1_1parser_1aedbd47dbeefeba9d1e3f8ed71f41aefc.html" title="Function template _globals">_globals()</a></code>. This global state object is ignored for all but the topmost parser; the topmost global state object is available in the semantic actions of all nested parsers. <code class="computeroutput">ErrorHandler</code> is the type of the error handler to be used on parse failure. This handler is ignored on all but the topmost parser; the topmost parser's error handler is used for all errors encountered during parsing. </p>

<p>Returns <code class="computeroutput">parser_((Arg &amp;&amp;)arg, (Args &amp;&amp;)args...)</code>. This is useful for those parsers that have <code class="computeroutput">operator()</code> overloads, e.g. <span style="color: red">&lt;lsquo&gt;&lt;/lsquo&gt;</span>char_('x<span style="color: red">&lt;rsquo&gt;&lt;/rsquo&gt;</span>)<span style="color: red">&lt;lsquo&gt;&lt;/lsquo&gt;</span>.

<p>This function does not participate in overload resolution unless <code class="computeroutput">parser_((Arg &amp;&amp;)arg, (Args &amp;&amp;)args...)</code> is well-formed. </p>
